As the combination of a database structure and word processing techniques were used to build the system, users can learn how to handle word processor and strengthen their data processing concept through practicing.

ABC Data Management System is also the main editor of TITES Multimedia Tutorial System and VIKON Multimedia Management System.

In the modern society, More and more of communications are being routed through electronic channels. E-mail is gradually replacing conventional letter. In any case we don't want our private message or confidential documents read by anyone else. However, Electronic messages are easy to be scanned by others. Since privacy is as apple-pie as the Constitution, there's nothing wrong with asserting our privacy.

VIKON Cryptography program is based on a simple algorithm called "random plus". Only one signature-file is needed to encode and decode files. This powerful cryptography technique allows users to exchange files or messages with privacy, authentication, and convenience. If you want to take your privacy into your own hands, this program is a wise choice for you.

An expert system is a computer program that uses knowledge, facts and reasoning techniques to solve problems and make decisions. Since Essential MYCIN (EMYCIN) successfully separated the interface engine from a knowledge base, several powerful rule-based expert system shells have been developed by software companies. These tools allow the knowledge engineer to create the knowledge base in an adaptive way and to group rules effectively.

Children Disease Diagnosis System was a bilingual expert system based on the knowledge base which was revised from DOCTOR written by Edward Reasor (1985). In the system, the knowledge base was presented in a graphic format. A Chinese hieroglyph data transfer program was designed to convert Chinese characters from black & white Hercules graphic to EGA color graphic.

The system was a pilot system of TITES (Taiwanese Intelligent Tutorial Expert System). Both systems were developed with Texas Instrument's Personal Consultant Plus.

Computer-assisted instruction (CAI) is a growing application of microcomputers in education. A wealth of literature exists on the subject. Multimedia typically refers to the combination of computer graphics, animation, optical storage, image and sound processing. With the advent of modern technologies, it is possible to integrate many types of media, text, graphics, video, and audio into one package.

Some research applying multimedia technology in education has been reported. These reports indicated that interactive multimedia instruction may be more effective and less costly than conventional instruction.

TITES (Taiwanese Intelligent Tutorial Expert System) was developed with Texas Instrument's Personal Consultant Plus in 1989. The design philosophy of TITES is to create an experimental environment for one of the knowledge navigators.

In the spring of 1992, the author reconstructed TITES with Microsoft BASIC PDS into a practical multimedia-based tutoring system. Together with a bilingual text editor and multimedia database, TITES offers a tool to enable teachers to generate teaching and testing material, to score tests, to record tutorial data, and to give instructions to students.

There are six elegant designs in the system:

	1. Integrated text, graphic, sound, animation, video and other 
	   related software.
	2. Easy to learn, easy to use.
	3. Combine the concept of word processor and database to design
 	   multimedia database and authoring tool.
	4. 1024x768 graphic solution, 256-color pictures, 24x24 various
 	   Chinese hieroglyph characters, MIDI, VOC, CMF files can be 
	   applied in the system.
	5. Flexible database and course-independent design.
	6. User friendly interface for external programs integration.
